2,289,880 issued to me July 14. 1942, and the ers now on the market; toprovide a dispensing container closure wherein practically all of theparts are formed of plastic or other non-rusting, non-corrodiblematerial, and further, to provide the dispensing closure with simple,practical and effective means for stirring the contents of the.

container simultaneous with the opening and closing of the valvularmeans that controls the discharge opening of the closure.

A further object of my invention is to provide novel and efficient formsof arms for the member that stirs the contents of the container to whichthe dispensing head is applied.

With the foregoing and other objects in view, my invention consists incertain novel features of construction and arrangement of parts whichwill be hereinafter more fully described and claimed and illustrated inthe accompanying drawings in which: l

Figs. 10, l1 and 12 are plan views of modied forms of the stirringmeans.

Fig. 13 is an enlarged section taken on the line |3-I'3 of Fig. 12.

Referring 'by numerals to the accompanying drawings which illustrate apreferred embodiment of my invention, I0 designates the circular body ofthe closure, the same having a convex upper surface and formed integralwith the mar- -(Ol. 259-117) My invention relates to adispensingcontainer y This container may be of any shape, may be formed of glass,plastic or metal and may contain any readily mobile powdered or granularsubstances, or heavy liquids, such vas oil, syrup, strained honey, orany of the liquid and semiliquid creams and soaps used by cosmeticians.

Extending outwardly and downwardly from the edge of body I II is ahandle i2 and projecting from said body diametrically opposite saidhandle is a pouring lip Il.

Formed in the convex top of body i0 and extending from the pouring lipI3 into the upper portion of'handle I2 is a groove or channel I4.Arranged to slide freely in groove I4 is a longitudinally curved plateI5. the forward end of ,which normally covers the pouring lip i3 andprojecting upwardly from the rear end of this plate is a short arm orlugi8 that is adapted to be engaged by the thumb of the users hand.

Plate I5 is retained for sliding movement in groove I4 by any suitablemeans, preferably small lips I'lwhich project from the top of body Ilover the side edges of said plate.

Interposed between the rear end of plate il and the rear end of grooveI4 is 'an expansive spring Il which yieldingly resists rearward movementof said plate.

Formed in the underside of the central portion of plate i5 is` a shortlongitudinally disposed recess i9 and formed along one side thereof is aseries of rack teeth 20.

Formed through plate i5' to the rear of recess i9 is an aperture 2i andformed through body Il rearwardly of said aperture when the plate is inits normal position is a longitudinally disposed slot 22.

Formed `through body i0 within pouring lip I3 is'an opening 23, throughwhich the contents of the container are dispensed and this opening isnormally covered by Journalled for rotation in a' bearing in the centerof body I0 is the upper portion 24 of a shaft 25 which extends downwardinto container C and mounted on the upper end of shaft portion 24 is apinion 26 which engages rack teeth 2l.

.Formed integral with or fixed to the'lower portion of shaft member 25,are the inner ends of a pair of oppositely arranged plates 2l and 28which have rubbing contact`.with the underface of body i0 and whichnormally close, re-

gin of the body is a depending flange I i, the lower portion of which isprovided with an internal thread which engages a corresponding externalthreadv on the upper end of the container C t0 which the closure isapplied.

spectively, the content discharge opening 23 and air inlet slot 22.

Formed integral with the lower portion of the sh-.aft 25 is a series ofstirring arms or ngers 2l.

4 the same being preferably arranged in pairs, withl the members of eachpair projecting from the shaft in opposite directions and each pairbeing arranged at 90 degrees relative to the next ad-v the lforward endof slidingl of the stirring arms are curved horizontally forward in thedirection of travel of said arms as the shaft is rotated by rearward, oropening movement of plate I8, which action takes place just prior to thetilting of the container and discharge of a portion of the contentsthereof.

Thus, the forwardly curved ends of the stirring arms, in their forwardmovement, plough through the contents of the container and tend to movethose portions of the contents immediately in front of said arms, towardthe center of said container thereby effecting the desired results.

In some instances it may be found desirable to move the sliding plate I5rearwardly several times before tilting the container to dispense aportion of its contents, for by such action, a very thorough stirring ofall of the contents of the container is accomplished.

. In Fig. 7 I'have shown a modied construction wherein the outer ends ofthe some of the stirring arms are extended upward and others downwardand said extended ends being widened as designated by 3l, whicharrangement provides for a very eii'ective stirring action in the.pulverized or liquid contents of the container.

To dispense a portion of the contents of container C, handle I2 isgrasped in the hand and by pressure of the thumb on lug I 6, plate I 5is drawn rearwardly thereby compressing spring I8 As the plate is thusmoved rearwardly, teeth engage and rotate pinion 26, thereby rotatingshaft carrying the arms or fingers 29 so that the same stir the contentsof the container and simultaneously, plates 21 and 28 are shifted so asto uncover slot 22, also discharge openings 23.

During the greater portion of the rearward travel of plate I5, and whilethe same is held in rearward position yto uncover opening 23, aperture2l registers with slot 22, thereby permitting air to enter the containerwhile a portion of the contents is discharging therefrom.

While plate I5 is held in rearward position the container is tilted soas to enable the contents of said container, or a portion thereof, todischarge through opening 23 and flow from lip I3 and when pressure onlug I6 is released. spring I8 will act to move plate I5 to its normalforward position, thereby closing opening 23 and moving aperture 2| outof registration with slot 22.

As plate I5 returns to its normal position shaft 25 is reversely rotatedand thus plates 21 and 28 are returned to their normal positions vtoclose opening 23 and slot 22 and thus said opening and slot are doublyclosed or cut of! to effectively prevent the ingress of air and theegress of any volatilization from the contents of the container.

It will be noted that the closing movement is effected by plate I5 inone direction and the rotary movement of plates 21 and 28 in directionsapproximately at right angles to the moveture wherein the stirring shaft2B* carries at its upper end, a short crank arm 3B which operates withina recess 36, in the underside of sliding plate I5'A and the pin on theend of said crank arm engages in a short transverse slot 31, lin plateIli.

Thus, as sliding plate I5s is shifted lengthwise the actuation of crankarm imparts rotary movement to the stirring shaft 25'.

In Fig. 10 I have shown the the stirring arms 29* carried by thestirring shaft curved throughout their lengths and in Fig. 11 the endsof the curved arms are shown provided on their ends with shorthorizontally disposed plates Il, that may have their forward edges 29sharpened so as to readily plough through the contents of the containerand stir same.

In Figs. 12 and 13 the stirring arms 40 which are curved throughouttheir lengths, are substantially V-shaped in horizontal section withtheir apices forwardly presented.

Thus it will be seen that I have provided a dispensing container that issimple, strong and 4durable in structure, inexpensive of manufacture andvery eifective in performing the functions for which it is intended.

It will be understood that minor changes in the size, form andconstruction of the various parts of my improved dispensing containermay be made and substituted for those herein shown and described withoutdeparting from the spirit of the invention, the scope of which is setforth in the appended claims.

I claim as my invention:

1. 'I'he combination with a container, of a closure detachably appliedto said container. said closure having a discharge opening. a handleprojecting from said closure, a spring pressed plate mounted for slidingmovement on said closure and normally closing said discharge opening,said closure provided with an air inlet opening, said plate providedwith an air inlet opening which registers with the air inlet opening inthe closure when said plate is at its rearward limit of movement, ashaft Journalled in the center of said closure and extending downwardlyinto said container, driving connections between said sliding plate andshaft, and a plate carried by said shaft and positioned against theunderface of said closure, which plate normally closes said dischargeopening and the air inlet opening in said closure, stirring fingersprojecting from said shaft.
